First, this function works fine in the multi interface too so it isn't only
for the easy interface.

Then, there's a range of callbacks that libcurl will or can call, and you can
call curl_easy_pause() from any or all of those, depending on your
application. I've used the progress callback in my test applications when I've
tested this feature.

If you have a need to pause a transfer, I figure you should also be able to
figure out how to unpause it! ;-)
